Member Function Documentation

RSocket * CBTCommunicator::ConnectL (  TPeerData *  aPeerData  ) 
 

Connects to a remote service.

Parameters:
aPeerData peer data
Returns:
connected socket

void CBTCommunicator::DiscoverPeersL (  const RMessage &  aMessage,
CServerSession &  aSession
) 
 

Discover all matching bluetooth peers.

Invoking this method will launch an active object that takes care of the actual discovery, and will call aMessage.Complete() upon completion of the discovery.

Parameters:
aSize pointer to size
aMessage original client-server call message
